Bulgaria Thursday commemorated the one-year anniversary of a deadly attack on an Israeli tourist bus on its soil and called for sanctions against Hizbullah, which is widely suspected of being behind the bombing.

Meanwhile, Lebanon has asked the European Union not to place Hizbullah on the list of terrorist groups – but if the EU decides to do so nonetheless, it will be in large part because of the Burgas bombing.

At a ceremony in the Black Sea resort of Burgas to mark the six dead and 35 wounded in the attack, Prime Minister Plamen Oresharski said the EU should "work towards a consensus decision that would allow... the military wing of Hizbullah to be added to its list of terror organizations."

EU foreign ministers will discuss on July 22 whether to add the powerful Lebanese Shiite movement to their list of terrorist groups.

Israel immediately blamed Iran and its "terrorist proxy" Hizbullah after the bombing, which killed five Israeli tourists and the Bulgarian driver of the bus at Burgas airport on July 18, 2012, in the deadliest attack on Israelis abroad since 2004.
